The problem of interfacing quantum mechanics and gravity has long been an unresolved issue in physics. Recent advances precision measurement technology suggest that detecting gravitational effects massive systems, particularly gravity-induced entanglement (GIE) the oscillator system, could provide crucial empirical evidence for revealing nature field. However, thermal decoherence imposes strict constraints on system parameters. Specifically, inequality $2 \gamma_m k_B T < \hbar G \Lambda...
The scattering of test fields by sandwich waves has been studied extensively. It found that for a variety fields, the energy scattered is amplified. In this paper, Scattering gravitational are calculated solving perturbations in wave background. Dependence their amplification with respect to parameters and incident examined. results show some cases, outgoing amplified as well.

The directional feature of Earth’s geomagnetic field has been contributing to the technological development and prosperity humankind since invention magnetic compass navigation centuries ago. Today, for instance, magnetoresistance sensors are commonly used in nanosatellites unmanned aerial vehicles high accuracy field-based mineral survey exploration.
In this paper, we introduce a generalized topological quantum field theory based on the symmetric monoidal category which call causal network condensation since it can be regarded as generalization of spin construction Baez, Turaev-Viro model and set theory. paper some new concepts, including category, diagrams, their gauge transformations. Based these nerve functor for category. It simplicial
